Title 50 › Chapter 36— FOREIGN INTELLIGENCE SURVEILLANCE › Subchapter II— PHYSICAL SEARCHES › § 1824
A judge can approve a physical search without telling the target when a federal officer applies and the Attorney General has OK’d the request. The judge must find probable cause that the target is a foreign power or an agent of one (a U.S. person cannot be called an agent just for exercising free speech), and that the place to be searched is connected to that target. The judge also must find that the applicant’s privacy rules (called minimization procedures) meet the law’s requirements and that the application includes all required statements and certifications. If the target is a U.S. person, the judge must not find the certifications clearly wrong based on the information given. The court order must say who or what is being searched, where, what can be taken or copied, how the search will be done and what privacy rules apply, and how long the search is allowed. The order must require following the privacy rules, let the applicant ask a landlord or custodian to help quietly and with little disruption, require secure record-keeping and fair payment for that help, and require the federal officer to report the results to the court quickly. Searches last only as long as needed or 90 days, whichever is shorter, except searches aimed at a foreign power or at a non‑U.S. agent may last up to one year or as requested. The judge may review whether privacy rules were followed. In an emergency, the Attorney General can authorize a search right away but must tell a Foreign Intelligence Surveillance Court judge and apply for court approval within 7 days; emergency searches must follow the privacy rules and stop when the information is obtained, the application is denied, or after 7 days. If no court order is issued, information from the search generally cannot be used in legal or government proceedings, and information about a U.S. person cannot be disclosed without consent except with Attorney General approval to prevent death or serious harm. The Attorney General must check compliance, and applications and orders must be kept for at least 10 years.
